Upgrading AOS 5.1.5 to 5.20.1.1 | Nutanix Community
Skip to main content

I need to upgrade an dark site cluster from AOS 5.1.5 to 5.20.1.1.   It looks like I need to upgrade from 5.1.5 to 5.5.9.5 to 5.10.11.1 to 5.15.6 to 5.20.1.1.   Will I need to upgrade the AHV matched to each version after I upgrade the AOS?

In this situation just to make sure that cluster doesn’t face downtime for the UVMs and assuming you have enough time for all the upgrades, you can upgrade the AHV to the “bundled AHV for the corresponding AOS”. It’s definitely not recommended for the AHV to be left far behind compared to AOS. Also, any dependencies about AOS upgrades should be answered through “pre-upgrade checks”
